Thanks to Mr. Russell Watson we got a neat tool for syntax coloring. fmSyntaxColorizer makes it very easy to customize the syntax coloring feature in our Filemaker Plugin, version 3.0. You can setup your own palette for colors, color script steps and calculations and simply apply all the colors.
Take a look at those images. And once 3.0 is available, download it. You'll find this database in the Third Party folder in examples.
Update: if you like, you can already take a look on this by downloading the 3.0 pr here: monkeybreadsoftware.de/filemaker/files. We are still working on some little improvements for the final 3.0 release.
